Add an Attachment in Outlook Web App
You can use attachments to include one or more files with any email message you send. Attachments can also be added to items in your Calendar, and to Tasks. When you add an attachment, you can choose a file from your hard drive, or a file you have in OneDrive for Business. You can send the file as an attachment, or as a link. When you send a link, not only will you save space in everyone's mailbox, but recipients are automatically given permission to edit the file, making it easier for everyone to collaborate. A file from your hard drive can be sent as a link by uploading it to OneDrive for Business.
Outlook Web App for Office 365 allows you to attach files, pictures, and messages to your new message.
